Figure 2.16: Predicted mean PE (pPE, based on 4000 simulated datasets) from the global model, namely the median pPE (triangle) including 50 % (thick bar) and 95 % CI (thin bar), as well as the distribution (polygon, only center and bottom panels) for all present combinations of Ac-Sc per site and method.
